ComboBox - Disabled and Collapsed item can still be selected

05-26-2009 1:53 AM |

A disabled combobox item can be selected if you use the arrows.

I tried setting IsEnabled=false and Visibility=Collapsed and still get the same behavior.

I find it to be a bit inconsistent.

If you can not select using the mouse you should not be able to select

using the keyboard either.

I am using Silverlight 3 ( I did not try it on SL 2).

 Why don't you remove those items from combobox instead of disabling them?

For most cases that's what I would do (filtering the source), but I have a specific situation where I don't want to.

The point is that the behavior is inconsistent, if you cannot select using the mouse, you

should not be able to select using the arrows.

The same functionality appears to exist with Silverlight 2.0 -- you can still select the item by using the keyboard.

It appears that the combobox items need to be declared as ComboBoxItems in order to disable one. I'm binding to a Dictionary<Enum, string> and can't figure out how to find and disable an item in the list.

Why dont you trigger a selection_Changed, and look for the item's IsEnabled or Collapsed - exit out of the routine if true. My two cents worth solution :D.
